HEAD RECEIVER SET.

Specification of Letters Patent.

Patented Dec. 31, 1918.

To all whom it may concern:

Be it known that I, BURTON L. LAw'roN, a citizen of the United States of America, residing at Meriden, Connecticut, have invented a new and useful Head Receiver Set, of which the following is a specification.

My invention relates to an improved headpiece or receiving set so called for telephonic or wireless receiving instruments, the same being of particular utility in connection with the latter use, wherein it is desired to have the two ear-pieces properly fitted and held against the ears so that the same may be worn with comfort and at the same time so that said ear-pieces will be positioned for the best results.

In the drawings:

Figure 1 is a front elevation of the complete apparatus.

Fig. 2 is a relatively enlarged. detail view.

Fig. 3 is a relatively enlarged cross sectional view of certain details taken on the line 3-3 of Fig. 2.

12 represent the two parts of what may be termed a head-band, the same being bowed and connected at its lower ends and being resilient so as to snugly fit over the top of the head. At the connected ends of the parts 1-2 I provide brackets which are each preferably provided with offsets 3-4,

each having holes arranged in line to receive rods 55. Each of the rods 5-5 is provided with a bifurcated extension 6 at its lower endarranged to receive between the ends thereof ear-pieces 7-? t which may lead the circuit wire or wires 88. The earpieces 7-7 arepivoted in the forked ends 6.6of the rods 5-5, and since the rods 55 are round and may be rotated in the extensions 3%, the ear-pieces 7-? may partake of a universal movement whereby the same will rest snugly and evenly against the ears. Inasmuch as the distance fromthe crown of the head to the cars varies in different individuals, it is necessary to provide means for securing vertical adjustment.

This vertical adjustment is eifected bv sliding, the rods 5-5 up and down in the aforesaid brackets until the desired adjustment is attained. The rods 5-5 are frictionally held in the adjusted position by friction springs 9-.9 or equivalent devices. In the particular form shown, the springs 99 are bowed and are held between the rear of each bracket and that part of each rod 5 that slides therethrough, as best seen in Figs. 1 and 3. The tension of the springs 99 against the rods is such as to cause suflicient wearer. if desired, set screws 10-10 may be provided whereby the rods 5-5 may be looked after the desired adjustment has been made. The particular means for frictionally holding and for locking the rods 5-5 in the adjusted position may be varied at will. I have, however, shown in the drawings a preferred form which is exceedingly simple, durable and effective. As shown in the drawings, the head-bands l-2 are preferably formed of central wire cores covered with a suitable fabric or flat braided material which causes the head-band: to rest easily on the head.

What I claim is;

1. in a headset of the character described, a head band, brackets at the opposite ends thereof provided with holes therethrough, a pair of ear-pieces, rods connected with said ear-pieces and extending through the holes in the brackets, and friction springs interposed between the brackets and said rods and bearing on said rods to oppose a frictional binding action to the sliding of the rods through the brackets.

2. In a head-set of the character described, a head band, brackets at the opposite ends thereof provided with holes therethrough, a pair of ear-pieces, rods fonnected with said ear-pieces and holes in the brackets, friction springs interposed betwcen the brackets and said rods and bearing on said rods to oppose a fricextending thrcugh the tional binding action to the sliding f the rods through the brackets, and means independent tively securing the rods in their adjusted positions in the brackets.

3. In a head-piece of the character de scribed, a resilient head-band portion, a

of said frictional devices for posibracket at each end thereof, each bracket having a plurality of ofisetsy said. offsets having alined holes therethrough, a pair of ear-pieces, a connection between each of said ear-pieces and said headban'd comprising a rod having a forked portion connected to r aeasaa posed between the offsets of the brackets and bearing on the rods engaged in said brackets to oppose a frictional binding force to the sliding of the rods through the brackets.

5. In a headset of the character described, the combination of a head band, a bracket at the endof said head band provided with. offset-s having alined holes therethrough, an ear-piece, a rod connected With said earpiece and slidingly engaged in the alined holes in said bracket, and a friction spring disposed between the ofisets and'bearing upon the rod to oppose a frictional binding force to the sliding of the rod through the bracket. 7
